Migrating from another Linux

I’m planning to migrate from Ubuntu to openSUSE. Has anyone done that with any form of success? Apart from blowing the machine away is there any easy way to do this?

I am running x86_64 and planning to remain on that.

Your problem is, you probably don’t have a separate /home partition in Ub.
So you will need to back up all your user data from your /home in Ub

You can no doubt use some of the settings and the email, data etc…

But really you will need to wipe the disc.
